Update to 1.5.0.
Since 1.5.0 swiftclient's setuptools have been using pbr thus adds pbr
dependancy.
The setup.py needs patching though to work correctly after merging
d2to1 into pbr 0.5.19. Hope this is temporary and setup.py will be
updated upstream soon.

This is a python client for the Swift API. There's a Python API (the
``swiftclient`` module), and a command-line script (``swift``).
This code is based on original the client previously included with
OpenStack's swift -- a highly available, distributed, eventually
consistent object/blob store.
